NCWR jacket and a chilly camp

Tried out both the NCWR jacket and the NOMAD jacket from TACUP Gear at a recent Bushcraft meet... I under estimated the cold though, so was a bit chilly on the night (stupidly left my Swanndri at home and an extra blanket... Thankfully the second night was a bit warmer!
I did however manage to use the NCWR jacket as en extra sleeping bivvy.. (I zipped it up and put it over the lower half of my body survival style!).. Which worked a treat.
I'm going to make some mods to the jacket which I will post up later.
Need to figure a better sleep system out.. Time for a Jervens bag I think!!
